Someone asked about eBooks on one of the library lists I'm on. They wanted to know what the prospects were. I responded on the list but I thought I'd share my opinion here as well.
I've never really understood the rationale behind these devices. I mean, I already have something that reads "electronic books" -- it's called a laptop. If I wanted something even more mobile, I'd get a smaller laptop -- or maybe use my PDA. The advantages of using my laptop -- besides the fact that I already own it -- is that I can play most formats on it, and not just one.
Furthermore, my laptop can do more than just "read" the thing -- I can cut out parts, re-use it, send it to friends and colleagues. I can link to the file, 'digg it', list it on del.icio.us. In other words, I can do everything I've become accustomed to do on a computer in a networked environment. Why would I want something that could do anything less?
I think if the sole purpose of a device is simply to serve as a platform for a proprietary format, it's doomed. This kind of "lock-in" is not popular with consumers. Just ask Sony how its own version of the iPod is doing.
